Ohio Rev. Code Ann. § 2907.171

The failure of the prosecuting attorney to give the notice required by section 2907.17 of the Revised Code does not give rise to a claim for damages against the prosecuting attorney or the county. The failure of the prosecuting attorney to give the notice does not constitute grounds for declaring a mistrial or new trial, for setting aside a conviction or sentence, or for granting postconviction relief to a defendant.
